“But there are limits to how responsibly companies can behave when behaving responsibly raises their costs and consumers are unwilling to pay higher prices. The most important constraint on the pursuit of virtue is the market”
David Vogel, Professor. Haas School of Business, University of California, Berkeley and author of The Market for Virtue: The Potential and Limits of Corporate Social Responsibility

Strategies for Handling Environmental Compliance
• Prevention• Treatment for Reuse
or Release• Release to the
Environment• Storage
![Page 29: Environmental Practices](https://reader036.vdocuments.site/reader036/viewer/2022062315/5681604b550346895dcf73bf/html5/thumbnails/29.jpg)
Prevention (avoids the problem of pollutants)
• Goes hand-in hand with cost reduction• Fuel efficiency• Lower Wastewater
Generation• Can take large capital
investment• Steam pulp dryer• Dry beet handling
![Page 30: Environmental Practices](https://reader036.vdocuments.site/reader036/viewer/2022062315/5681604b550346895dcf73bf/html5/thumbnails/30.jpg)
Treatment for Reuse or Release (Removes or reduces pollutants to acceptable levels)
• Treatment for Reuse• wastewater• waste lime
• Treatment for Release• Stack Gasses• wastewater
• Treatment systems often generate their own wastes• dust (particle removal)• sludge (wastewater
treatment)
![Page 31: Environmental Practices](https://reader036.vdocuments.site/reader036/viewer/2022062315/5681604b550346895dcf73bf/html5/thumbnails/31.jpg)
Release into Environment
• Limited Capacity to accept Pollutants
• Highly Regulated• Carefully Monitored
![Page 32: Environmental Practices](https://reader036.vdocuments.site/reader036/viewer/2022062315/5681604b550346895dcf73bf/html5/thumbnails/32.jpg)
Almost all Discharges Are Regulated
• EPA• State Department of
Health • Tribal Environmental
Council• County Board• City Council
![Page 33: Environmental Practices](https://reader036.vdocuments.site/reader036/viewer/2022062315/5681604b550346895dcf73bf/html5/thumbnails/33.jpg)
Penalties for not Obeying Environmental Rules
• Civil and Criminal • Fines• Jail• Disqualification• Escalating
![Page 34: Environmental Practices](https://reader036.vdocuments.site/reader036/viewer/2022062315/5681604b550346895dcf73bf/html5/thumbnails/34.jpg)
Discharging to the Environment is Costly
• Large Amount of Material• Compliance Costs
• Permitting• Pre-discharge costs• Discharge monitoring• Post-discharge costs
• Fines if there are problems
![Page 35: Environmental Practices](https://reader036.vdocuments.site/reader036/viewer/2022062315/5681604b550346895dcf73bf/html5/thumbnails/35.jpg)
Temporary and Permanent Storage (Staging Areas, Landfills and Ponds)
• Ownership and Operations
• Permitting• Ongoing Care• Liability
![Page 36: Environmental Practices](https://reader036.vdocuments.site/reader036/viewer/2022062315/5681604b550346895dcf73bf/html5/thumbnails/36.jpg)
Strategy for Environmental Protection must Balance many Issues
• Balance Costs and Benefits
• Should fit into larger corporate strategy
• Should consider outside stakeholders
• Should consider short- and long-term consequences
![Page 37: Environmental Practices](https://reader036.vdocuments.site/reader036/viewer/2022062315/5681604b550346895dcf73bf/html5/thumbnails/37.jpg)
Environmental Stewardship is the Right Thing
• Protects Nature• Good Neighbor• Reduces Expenses
(can make money)• Prevents Trouble• Part of the Job
